Countersteering as a concept is also use in flying (i.e., not just single-track vehicles on the ground). It's always required to stop a turn, and may be required to maintain a constant (steep) turn, depending on the plane geometry. But in flying and in riding motorcycles, it's dangerous to fly/ride by thinking, e.g., "counter-steer before the turn". It all depends on you and the machine, and there are other ways to do things. For example, throwing your weight around also changes the center of gravity. On a dirt bike, sliding friction can enable you to be lower than you would otherwise, and sliding acceleration can help you be higher. The question is what happens in the inevitable case you get it wrong. In dirt if you're low while accelerating and start to high-side, typically you'll instinctively drop the throttle, which is the right thing. On a road bike you want to have some degrees of freedom left both in how low your body is and how much you're asking of the tires, so if you're too low you can in-steer (taxing the tires more) without losing road grip. So it's great to plan by thinking, but in a moment of hard riding/flying, it's much more important to feed everything through the cerebellum and not the cerebral cortex, and to have margins for responding to dynamic instability that track instinctive responses. I.e., actually practice racing and aerobatics.
